Most people never gets out of the kind of basement, the fun is the spider. It could have been a lot better if the player didn't looked like a dwarf!

Hi no Tori, an adventure shmup? for MSX2. Goal is to collect tablets to open doors to eventually collect the 5 key items to fight the final boss. Stages loop vertically and horizontally, so you have to figure out the correct way thru the stages. 🔥🐦 www.youtube.com/watch?v=ofAV...

Ambitious developer showcases slick triple-level Quake-like game stored in tiny 64KB executable — every game asset tucked inside what could be a ‘rounding error’ in modern app payload terms And id Software’s Qtest multiplayer-only demo of Quake was released exactly 30 years ago today.

Can I also remind people that this music was composed using a text editor. No sequencer or real instruments were used, just commands, notes, duration and data typed into the editor/assembler we used to build the game. Here's an example from NES Solstice. Each channel had its own list of instructions

I knew about Altirra, but I didn't know about this hardware reference, so cool! BTW, so impressed with Avery Lee having written a new and faster BASIC for the Atari. It reminds me of my Extended ECS BASIC nanochess.org/ecs_basic.html

I bought an Atari 130XE and it entered directly into RAM test mode. I had to replace four memory chips, and made it to enter BASIC. Unfortunately the keyboard mylar is faulty, but I can play games with the joystick. #retro #retrogaming #Atari

This is the Casio #WQV-1, the world's first camera watch. Originally you would sync via an IR serial dongle on Win98, but most of the IR pods are long gone. I made a device that syncs, converts, and mounts as a USB drive to get your photos!

Nope. MODE is the CVBasic statement to select video mode and by default starts in MODE 0. It isn't referred to the TI hardware mode nor the MSX BASIC definitions.

CVBasic now supports MODE 4 for MSX2 (similar to MODE 0 but enables extended sprites) and DEFINE SPRITE COLOR for selecting sprites color. I've also added viboritas_msx2.bas to show how to do OR'ed sprites for 3 colors. #retro #retrogaming #msx

If you have one of these, CVBasic now handles the spinners and Roller Controller for the Colecovision. You only need to read it using CONT1.SPINNER and CONT2.SPINNER. Compile the bleeding-edge code from git github.com/nanochess/cv... #retro #retrogaming #colecovision

Picked up @nanochess.bsky.social’s port of Akalabeth for Intellivision. It’ll be on deck for next game.

Find myself wishing it had a digital rom for the Sprint but it’ll be some time before that becomes normal, if ever.
